Ever wonder what those yellow numbers on the gas pump mean? These are called the 'octane rating'. The octane rating tells you how much the fuel can be compressed inside an engine before it ignites on its own. The higher the rating, the more the fuel can be compressed before igniting. That's why many high-performance engines require the higher level (and unfortunately the higher priced) octane gas at the pump. If you've ever heard your engine make a knocking sound, you know it's bad - but did you know that your gas is igniting without the help of the engine's spark plugs? You may want to think about switching to a higher-octane fuel, and bring your car in! We'll give you a free inspection!
